Nested params (ala Ruby on Rails or PHP-style param arrays)

Ruby on Rails has a nice feature to create nested parameters that help
with the organization of data in a form - parameters can be an
arbitrarily deep nested structure.

The way this structure is denoted is that when you construct a form the
field names have a special syntax which is parsed.

This plugin supports two syntaxes

dot notation

<input name="foo.bar.gorch" />

subscript notation

<input name="foo[bar][gorch]" />

When reading query parameters from $c->req you can now access all the
items starting with “foo” as one entity using $c->req->param’foo’;.
Each subitem, denoted by either the dot or the square brackets, will be
returned as a further deeper hashref.
